Circuit board and lighting device having the circuit board

Abstract

Provided is a circuit board including: a supporting substrate; light emitting elements mounted to the supporting substrate; a through hole passing through the supporting substrate; and a connector inserted into the through hole and for supplying an electric current to the light emitting elements.

What is claimed is: 
     
       1. A circuit board, comprising:
 a supporting substrate; 
 a plurality of light emitting elements mounted to the supporting substrate; 
 a through hole passing through the supporting substrate; and 
 a connector inserted into the through hole and supplying an electric current to the light emitting elements, 
 wherein the through hole is formed at a position corresponding to a position between the light emitting elements, and 
 wherein the supporting substrate comprises a first region and a second region extending to be bent from the first region. 
 
     
     
       2. The circuit board of  claim 1 , wherein the light emitting elements are mounted to one surface of the first region of the supporting substrate, and the circuit board further comprises a pad portion having pad wirings connected to the light emitting elements on the one surface of the first region; and a string portion having string wirings for transmitting electrical signals to the light emitting elements. 
     
     
       3. The circuit board of  claim 2 , further comprising a bending hole formed in a bending portion between the first region and the second region. 
     
     
       4. A lighting device, comprising:
 a circuit board of  claim 1 ; and 
 an outer housing including an external through hole at a position corresponding to the position of the through hole of the circuit board. 
 
     
     
       5. A circuit board, comprising:
 a supporting substrate; 
 a plurality of light emitting elements mounted to the supporting substrate; and 
 a through hole formed in the supporting substrate, and into which a connector for supplying currents to the light emitting elements is inserted, 
 wherein the through hole is formed at a position corresponding to a position between the light emitting elements, and 
 wherein the supporting substrate comprises a first region and a second region extending to be bent from the first region. 
 
     
     
       6. The circuit board of  claim 5 , wherein the light emitting elements are mounted to one surface of the first region, and the circuit board further comprises a pad portion having pad wirings connected to the light emitting elements on the one surface of the first region, and a string portion having string wirings for transmitting electrical signals to the light emitting elements. 
     
     
       7. The circuit board of  claim 6 , further comprising a bending hole formed in a bending portion between the first region and the second region.
